TE Connectivity 1-1971875-3 Rectangular Connector Housing Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-1971875-3 is a 9-position rectangular connector receptacle housing from the Power Triple Lock, High Temp series. This component serves as the housing structure for panel-mount applications requiring crimp-terminated tab contacts. The part is manufactured in natural-colored Polybutylene Terephthalate (PBT) and operates across an extended temperature range of -55°C to 105°C.

Equivalent and substitute parts are identified when design requirements, inventory constraints, or application specifications necessitate alternative housing options that maintain electrical and mechanical compatibility within the same connector family.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1-1971875-3 are qualified based on the following critical parameters that determine functional and mechanical interchangeability:

Primary Substitution Criteria:

• Connector type (Receptacle)
• Number of positions (9)
• Pitch spacing (0.236" / 6.00mm)
• Number of rows (3)
• Row spacing (0.319" / 8.10mm)
• Mounting configuration (Panel Mount, Snap-In)
• Contact termination method (Crimp)
• Fastening mechanism (Latch Lock)
• Operating temperature range (-55°C ~ 105°C)
• Contact type (Tab)

Secondary Variation Parameters:

• Housing color (Natural vs. Gray)
• Insulation material (PBT vs. Polyamide PA6)
• Series designation (Power Triple Lock, High Temp vs. Power Triple Lock)

Parts meeting all primary criteria are classified as parametric equivalents. Variations in housing color and insulation material do not affect electrical or mechanical compatibility when all primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

1-1971875-3 (Primary Part)

The 1-1971875-3 is the original specification part, manufactured in natural-colored PBT insulation material. This part carries ROHS3 Compliant certification and is actively produced. Selection of this part is appropriate when the original design specification calls for natural housing color or when PBT material properties are specifically required for the application.

5-1971875-3 (Parametric Equivalent - Recommended Primary Substitute)

The 5-1971875-3 is a direct parametric equivalent differing only in housing color (Gray) and insulation material (PBT, identical to primary part). This part carries RoHS Compliant certification with REACH Unaffected status. Higher inventory availability (1538 pcs vs. 846 pcs) makes this part suitable for high-volume applications or when gray housing color is acceptable. All electrical and mechanical characteristics remain identical to the primary part.

5-2232356-3 (Parametric Equivalent - Alternative Material Option)

The 5-2232356-3 maintains all critical electrical and mechanical parameters but substitutes the insulation material with Polyamide (PA6) Nylon 6, Glass Filled. This part carries RoHS Compliant certification and offers the highest inventory availability (1582 pcs). Selection of this part is appropriate when polyamide material properties are compatible with application requirements and when gray housing color is acceptable. The glass-filled nylon composition provides enhanced mechanical strength compared to PBT.

All three parts are active products with unlimited moisture sensitivity levels and identical operating temperature ranges. Selection between these parts should be based on material compatibility requirements, housing color specifications, and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can 5-1971875-3 be used as a direct replacement for 1-1971875-3?

A: Yes. The 5-1971875-3 is a parametric equivalent with identical electrical and mechanical specifications. The only differences are housing color (Gray vs. Natural) and base product number designation. All critical parameters including pitch, row spacing, position count, mounting type, and operating temperature are identical.

Q: What is the difference between 5-1971875-3 and 5-2232356-3?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The primary difference is insulation material: 5-1971875-3 uses Polybutylene Terephthalate (PBT), while 5-2232356-3 uses Polyamide (PA6) Nylon 6, Glass Filled. Both materials support the full -55°C to 105°C operating temperature range. Material selection depends on application-specific requirements for mechanical strength, chemical resistance, or thermal properties.

Q: Are contacts included with these connector housings?

A: No. All three parts (1-1971875-3, 5-1971875-3, and 5-2232356-3) are housings only. Contacts must be procured separately and are not included in the package.

Q: Do all substitute parts have the same RoHS compliance status?

A: The primary part (1-1971875-3) carries ROHS3 Compliant certification. Both substitute parts (5-1971875-3 and 5-2232356-3) carry RoHS Compliant certification. All three parts meet RoHS requirements and are suitable for applications requiring RoHS compliance.

Q: Can housing color affect electrical performance?

A: No. Housing color is a cosmetic specification only and does not affect electrical performance, impedance, or signal integrity. Selection between Natural (1-1971875-3) and Gray (5-1971875-3 or 5-2232356-3) should be based on design documentation or application aesthetics only.

Q: What is the significance of the base product number difference?

A: The base product number (1971875 vs. 2232356) indicates different product lines within the TE Connectivity AMP Connectors portfolio. Despite different base numbers, parts 1-1971875-3 and 5-2232356-3 maintain identical electrical and mechanical specifications and are fully interchangeable when all primary parameters align.

Q: Are all three parts suitable for panel-mount applications?

A: Yes. All three parts feature Panel Mount, Snap-In mounting configuration with identical row spacing (0.319" / 8.10mm) and pitch (0.236" / 6.00mm). They are mechanically interchangeable in panel-mount installations.

Q: What does Moisture Sensitivity Level (MSL) 1 mean?

A: MSL 1 (Unlimited) indicates that these connector housings have unlimited shelf life and do not require special moisture-control storage conditions. No baking or desiccant storage is required prior to assembly.
