GDH06S Equivalent & Substitute Parts

Part Overview

The GDH06S is a surface mount DIP switch manufactured by TE Connectivity ALCOSWITCH Switches. This component is a single-pole single-throw (SPST) slide switch with 6 positions, rated for 25mA at 24VDC operation. The GDH06S is classified as obsolete product status, necessitating identification of equivalent and substitute components for ongoing design support and procurement requirements. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts provide functional alternatives with acceptable parameter variations within engineering tolerances.

Substitute Part Grouping Explanation

Substitution eligibility for the GDH06S is determined by strict equivalence across the following critical parameters: circuit configuration (SPST), number of positions (6), current rating (25mA), voltage rating (24VDC), actuator type (slide standard), mounting type (surface mount), termination style (gull wing), and pitch (0.050" half). All identified substitute parts maintain these core electrical and mechanical specifications.

Substitute parts are classified into two categories:

Direct Equivalents maintain all specified parameters with only packaging or product status differences. These parts are functionally interchangeable without design modification.

Similar Alternatives maintain all critical electrical parameters and core mechanical specifications but may exhibit variations in secondary characteristics such as height above board, body material, contact material composition, or operating temperature range. These parts require engineering evaluation for specific application constraints.

Engineering Selection Recommendations

1571983-8 (TE Connectivity ALCOSWITCH)

The 1571983-8 is the primary direct equivalent for the GDH06S. This part maintains identical electrical specifications (25mA, 24VDC, SPST, 6 positions), mechanical configuration (surface mount, gull wing termination, 0.050" pitch), and operating temperature range (-30°C ~ 85°C). The 1571983-8 is classified as active product status with ROHS3 compliance, providing long-term availability and regulatory alignment. Packaging is supplied in tube format. This part is suitable for direct substitution in all applications where the GDH06S was originally specified.

218-6LPST (CTS Electrocomponents)

The 218-6LPST is a direct equivalent from an alternative manufacturer. All critical electrical parameters match the GDH06S (25mA, 24VDC, SPST, 6 positions), and mechanical specifications are equivalent (surface mount, gull wing termination, 0.050" pitch). The 218-6LPST offers an extended operating temperature range (-55°C ~ 85°C) compared to the GDH06S (-30°C ~ 85°C), providing enhanced performance in low-temperature environments. Height above board is 0.104" (2.65mm) versus 0.091" (2.30mm) for the GDH06S, requiring clearance verification in space-constrained layouts. Contact material is beryllium copper rather than copper alloy. The 218-6LPST is active product status with ROHS3 compliance and tube packaging.

97R06ST (Grayhill Inc.)

The 97R06ST is a similar alternative maintaining all critical electrical specifications (25mA, 24VDC, SPST, 6 positions) and core mechanical characteristics (surface mount, gull wing termination, 0.050" pitch). The 97R06ST exhibits reduced height above board (0.061" versus 0.091"), beneficial for applications with vertical space constraints. Operating temperature range is -40°C ~ 85°C, narrower than the GDH06S at the low end. Body material is polyamide (PA) nylon rather than polyphenylene sulfide (PPS). The 97R06ST is active product status with ROHS3 compliance, washable construction, and tube packaging.

97R06T (Grayhill Inc.)

The 97R06T is a similar alternative with identical electrical specifications to the GDH06S (25mA, 24VDC, SPST, 6 positions) and equivalent mechanical configuration (surface mount, gull wing termination, 0.050" pitch). The 97R06T provides the same reduced height above board as the 97R06ST (0.061" versus 0.091"). Operating temperature range is -40°C ~ 85°C. Body material is polyamide (PA) nylon. The 97R06T differs from the 97R06ST in washability; the 97R06T is not washable. The 97R06T is active product status with ROHS3 compliance and tube packaging.

Frequently Asked Questions (FAQ)

Q: Can the 1571983-8 be used as a direct replacement for the GDH06S without design modification?

A: Yes. The 1571983-8 maintains identical electrical ratings (25mA, 24VDC), circuit configuration (SPST), position count (6), actuator type (slide standard), mounting method (surface mount), termination style (gull wing), pitch (0.050"), and operating temperature range (-30°C ~ 85°C). No design modification is required for direct substitution.

Q: What is the primary difference between the 218-6LPST and the GDH06S?

A: The 218-6LPST maintains all critical electrical and mechanical specifications but offers an extended low-temperature operating range (-55°C versus -30°C). Height above board is 0.104" compared to 0.091" for the GDH06S. Contact material is beryllium copper rather than copper alloy. These differences require clearance verification in space-constrained applications and evaluation of contact material compatibility with specific circuit requirements.

Q: Why do the Grayhill 97R06ST and 97R06T parts have lower height above board specifications?

A: The 97R06ST and 97R06T are designed with reduced profile (0.061" versus 0.091"), making them suitable for applications with vertical space constraints. This is a design characteristic of the Grayhill series and does not affect electrical performance. PCB layout and enclosure clearance must be evaluated for compatibility.

Q: Are all substitute parts RoHS compliant?

A: The GDH06S is RoHS non-compliant. All identified substitute parts (1571983-8, 218-6LPST, 97R06ST, 97R06T) are ROHS3 compliant. This compliance status must be considered for applications subject to RoHS regulatory requirements.

Q: What is the difference between the 97R06ST and 97R06T?

A: Both parts are electrically and mechanically equivalent. The primary difference is washability: the 97R06ST is washable, while the 97R06T is not washable. Selection depends on manufacturing process requirements for PCB cleaning and flux removal.

Q: Can the 218-6LPST be used in applications requiring the original -30°C ~ 85°C operating temperature range?

A: Yes. The 218-6LPST operating temperature range (-55°C ~ 85°C) encompasses the GDH06S range (-30°C ~ 85°C). The extended low-temperature capability provides additional margin but does not restrict use within the original temperature specification.

Q: What packaging formats are available for these substitute parts?

A: All identified substitute parts are supplied in tube packaging. The GDH06S packaging format was not specified in the original documentation. Tube packaging is standard for surface mount DIP switches and is compatible with automated assembly processes.

Q: Are there any body material considerations when selecting between substitute parts?

A: The GDH06S uses polyphenylene sulfide (PPS) body material. The 1571983-8 maintains PPS construction. The 218-6LPST body material is not specified. The Grayhill parts (97R06ST, 97R06T) use polyamide (PA) nylon. Material selection may affect chemical resistance, thermal stability, and mechanical properties in specific environmental conditions. Application requirements should guide material selection.

Q: What is the mechanical life specification for the 218-6LPST?

A: The 218-6LPST mechanical life specification is not provided in the available documentation. The GDH06S specifies 1,000 cycles mechanical life. Clarification from the manufacturer is required if mechanical life is a critical design parameter.
