Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 48ASSP3S1M7RAT is determined by strict alignment of the following electrical and mechanical parameters:

Mandatory Matching Parameters:

• Circuit type: SPDT configuration
• Switch function: On-Off-On operation
• Current rating: 0.4VA (AC/DC)
• Voltage rating: 20V AC and 20V DC
• Termination style: PC Pin
• Contact finish: Gold plating
• Mounting orientation: Right Angle, Vertical

Acceptable Variation Parameters:

• Mounting method: Panel Mount (main part) vs. Through Hole (substitute parts) — both accommodate vertical right-angle installation
• Actuator length: 5.08mm (main) vs. 4.70mm–4.72mm (substitutes) — within acceptable mechanical tolerance
• Switch travel: 2.16mm (main) vs. 2.16mm–2.20mm (substitutes) — functionally equivalent
• Electrical life cycles: 30,000 (main) vs. 60,000–100,000 (substitutes) — substitutes exceed minimum requirement
• Operating temperature: -30°C to 85°C (main) vs. -30°C to 65°C (C&K substitute) — main part and APEM substitute cover full range

The identified substitutes (1103M2S3AV2BE2 and GH39WW00001) meet all mandatory electrical parameters and maintain functional compatibility despite minor mechanical variations.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (48ASSP3S1M7RAT): The Grayhill 48ASSP3S1M7RAT remains the specified component when panel mount configuration is required. This part is Active status, RoHS Compliant, and REACH Unaffected. Operating temperature range extends to 85°C, supporting applications in elevated thermal environments.

Substitute Selection (1103M2S3AV2BE2 - C&K): The C&K 1103M2S3AV2BE2 is suitable when through-hole mounting is acceptable and operating temperatures do not exceed 65°C. This substitute provides extended electrical life (100,000 cycles vs. 30,000 cycles), offering enhanced durability for high-cycle applications. ROHS3 Compliant status and REACH Unaffected designation maintain regulatory alignment.

Substitute Selection (GH39WW00001 - APEM): The APEM GH39WW00001 is suitable when through-hole mounting is acceptable and full operating temperature range (-30°C to 85°C) is required. This substitute provides 60,000 electrical life cycles and glass-filled nylon actuator material. ROHS3 Compliant status and REACH Unaffected designation maintain regulatory alignment.

All three parts share identical electrical specifications (0.4VA, 20V AC/DC, SPDT, On-Off-On), gold-plated contacts, and PC pin termination. Selection between substitutes depends on mounting method availability and operating temperature requirements within the target application.

Frequently Asked Questions (FAQ)

Q: Can the C&K 1103M2S3AV2BE2 replace the Grayhill 48ASSP3S1M7RAT in all applications?

A: The C&K substitute is electrically equivalent but differs in two aspects: (1) mounting method is through-hole rather than panel mount, and (2) maximum operating temperature is 65°C versus 85°C for the Grayhill part. Substitution is valid only when the application accommodates through-hole installation and operates within the -30°C to 65°C temperature range.

Q: What is the significance of the electrical life rating difference (30,000 vs. 100,000 cycles)?

A: Electrical life indicates the number of switching cycles the contact can withstand before degradation. The Grayhill part specifies 30,000 cycles; the C&K substitute specifies 100,000 cycles. For applications requiring frequent switching, the C&K substitute provides extended operational life. For low-cycle applications, both parts meet functional requirements.

Q: Are there differences in contact material between the three parts?

A: Yes. The Grayhill part uses copper alloy contacts; the C&K part uses copper contacts; the APEM part uses brass contacts. All three are gold-plated. These material variations are within acceptable substitution parameters for 0.4VA, 20V SPDT applications, as contact material selection does not alter the electrical performance at these ratings.

Q: What is the impact of actuator length variation (5.08mm vs. 4.70–4.72mm)?

A: Actuator length affects the physical profile and engagement depth. The Grayhill part has a longer actuator (5.08mm) compared to substitutes (4.70–4.72mm). This difference is acceptable when mechanical clearance and user interface requirements accommodate the shorter actuator length. Panel mount vs. through-hole mounting methods also influence how actuator length impacts installation.

Q: Can the APEM GH39WW00001 be used in applications requiring the full -30°C to 85°C operating range?

A: Yes. The APEM part specifies -30°C to 85°C operating temperature, matching the Grayhill part's full range. The C&K substitute is limited to -30°C to 65°C and is not suitable for applications requiring operation above 65°C.

Q: Are all three parts RoHS compliant?

A: Yes. The Grayhill part is RoHS Compliant; both substitutes are ROHS3 Compliant. All three parts are REACH Unaffected and classified as EAR99 for export control purposes.

Q: What is the difference between panel mount and through-hole mounting for this switch type?

A: Panel mount (Grayhill) is secured directly to an equipment panel or enclosure face with the switch body mounted perpendicular to the panel surface. Through-hole (C&K and APEM) requires the switch leads to pass through holes in a printed circuit board or mounting surface. Selection depends on the target installation method and available mounting infrastructure.
