TE Connectivity AMP Connectors 8-1971875-4 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 8-1971875-4 is a 12-position rectangular connector receptacle housing designed for panel mount, snap-in applications. This connector operates across a temperature range of -55°C to 150°C and features a 6.00mm pitch with three rows of contacts. The part is classified as Active product status and is RoHS Compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Substitute parts become necessary when the primary part number experiences inventory constraints, supply chain disruptions, or when design requirements permit alternative configurations that maintain electrical and mechanical compatibility within specified parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector housings is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Receptacle
• Number of Positions: 12
• Pitch: 0.236" (6.00mm)
• Number of Rows: 3
• Row Spacing: 0.319" (8.10mm)
• Mounting Type: Panel Mount, Snap-In
• Contact Termination: Crimp
• Fastening Type: Latch Lock
• Contact Type: Tab
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part 5-2232356-4 maintains equivalence across all mandatory parameters. Variations in color (Natural versus Gray), insulation material composition (PA versus PA6 Glass Filled), and operating temperature range do not prevent substitution when the mechanical interface and electrical termination requirements remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both 8-1971875-4 and 5-2232356-4 are Active product status components manufactured by TE Connectivity AMP Connectors and maintain full compliance with RoHS regulations. Both parts carry MSL 1 (Unlimited) moisture sensitivity classification.

Selection between these parts is determined by application operating temperature requirements. The main part 8-1971875-4 supports continuous operation to 150°C, while substitute 5-2232356-4 operates to 105°C maximum. Applications requiring sustained operation above 105°C must use the main part number.

For applications operating within the -55°C to 105°C range, both parts are electrically and mechanically equivalent. The substitute part 5-2232356-4 offers higher current inventory availability (1007 pieces versus 862 pieces) and maintains identical mechanical interface specifications.

Frequently Asked Questions (FAQ)

Q: Can 5-2232356-4 be used as a direct replacement for 8-1971875-4 in all applications?

A: Direct replacement is valid only for applications with maximum operating temperatures not exceeding 105°C. The substitute part has a lower upper temperature limit (105°C versus 150°C). Applications requiring operation above 105°C must use the original part number 8-1971875-4.

Q: Are the mechanical dimensions identical between these two parts?

A: Yes. Both parts share identical pitch (6.00mm), row spacing (8.10mm), number of positions (12), number of rows (3), mounting type (Panel Mount, Snap-In), and fastening mechanism (Latch Lock). The connector housings are mechanically interchangeable.

Q: What is the difference in insulation material between these parts?

A: The main part 8-1971875-4 uses standard Polyamide (PA) Nylon insulation. The substitute 5-2232356-4 uses Polyamide (PA6) Nylon 6 with glass filler. Both materials are polyamide-based and maintain equivalent electrical properties within their respective operating temperature ranges.

Q: Do both parts require the same contact specifications?

A: Yes. Both housings accept identical crimp-terminated tab contacts. The contact specifications are not included with the housing and must be sourced separately. Contact compatibility is determined by the 6.00mm pitch and tab contact type, which are identical across both parts.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS compliant. The main part carries RoHS Compliant status, while the substitute carries ROHS3 Compliant status. Both meet current regulatory requirements. Both parts have MSL 1 (Unlimited) moisture sensitivity classification.

Q: Does the color difference (Natural versus Gray) affect electrical performance?

A: No. Color is a cosmetic specification only and does not affect electrical or mechanical performance. Selection between Natural and Gray is based on application aesthetics or internal documentation requirements.

Q: What is the current inventory status for each part?

A: The main part 8-1971875-4 has 862 pieces in stock. The substitute part 5-2232356-4 has 1007 pieces in stock. Both are classified as New Original In Stock.
