TE Connectivity AMP Connectors 52957 Spade Terminal Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 52957 is an insulated spade terminal connector designed for crimp termination of 14-16 AWG wire. This blue Plasti-Grip series terminal features a 10 stud configuration with tin-plated brass contacts and serrated termination for secure wire attachment. The component is classified as Active product status and is suitable for free-hanging, in-line mounting applications. Substitute parts are identified when packaging format changes, compliance certifications differ, or inventory availability requires alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution between TE Connectivity AMP Connectors 52957 and 52957-1 is valid based on identical electrical and mechanical parameters. Both parts maintain the same wire gauge (14-16 AWG), stud size (10 Stud), terminal type (Spring, Snap), termination method (Crimp), contact material (Brass), contact finish (Tin), insulation material (PVC), color (Blue), and all dimensional specifications including width, length, and tongue opening.

The primary difference between these parts is packaging format: 52957 is supplied in Bulk packaging, while 52957-1 is supplied in Cut Tape (CT) packaging. This distinction affects inventory management and automated assembly processes but does not alter the functional or mechanical compatibility of the terminal connector.

Both parts are classified as Active product status and are manufactured by TE Connectivity AMP Connectors within the Plasti-Grip series. The substitution is valid for applications requiring identical terminal specifications with alternative packaging delivery methods.

Parameter Comparison

Engineering Selection Recommendations

Both TE Connectivity AMP Connectors 52957 and 52957-1 are Active product status components suitable for direct substitution in applications requiring 14-16 AWG insulated spade terminals with 10 stud configuration.

Part 52957-1 carries ROHS3 compliance certification, making it the preferred selection for applications subject to Restriction of Hazardous Substances regulations. Part 52957 is listed as "Not applicable" for RoHS status, indicating it may not meet current regulatory requirements for restricted substance compliance.

Selection between these parts should be based on:

1. Regulatory compliance requirements: ROHS3 compliance is required for 52957-1; not applicable for 52957
2. Packaging requirements: Bulk packaging for 52957; Cut Tape packaging for 52957-1
3. Inventory availability: 52957 has 672 pieces in stock; 52957-1 has 14,608 pieces in stock
4. Assembly process compatibility: Bulk packaging suits manual assembly; Cut Tape packaging suits automated pick-and-place systems

All other electrical and mechanical parameters are identical between both parts, ensuring functional equivalence in terminal performance, wire gauge compatibility, and mechanical fit.

Frequently Asked Questions (FAQ)

Q: Can 52957-1 be used as a direct replacement for 52957?

A: Yes. Both parts are electrically and mechanically identical. The 52957-1 differs only in packaging format (Cut Tape versus Bulk) and RoHS compliance status. All terminal specifications, wire gauge ratings, stud sizes, and dimensional parameters are identical.

Q: What is the difference between Bulk and Cut Tape packaging?

A: Bulk packaging supplies components loose in a container, suitable for manual assembly and hand-picking operations. Cut Tape packaging supplies components on a continuous tape strip, designed for automated pick-and-place assembly equipment. The terminal itself is identical in both formats.

Q: Does the RoHS compliance difference affect terminal performance?

A: No. RoHS compliance relates to the manufacturing process and material sourcing restrictions, not terminal electrical or mechanical performance. Both parts function identically in circuit applications. RoHS3 compliance (52957-1) is required for applications subject to hazardous substance regulations; the non-applicable status of 52957 indicates it may not meet these regulatory requirements.

Q: Are the dimensional specifications identical between 52957 and 52957-1?

A: Yes. Both parts have identical width (0.406" / 10.31mm), overall length (0.920" / 23.37mm), tongue inside opening (0.190" / 4.83mm), and insulation diameter range (0.118" ~ 0.193" / 3.00mm ~ 4.90mm).

Q: Which part should be selected for new designs?

A: Part 52957-1 is recommended for new designs due to ROHS3 compliance certification and significantly higher inventory availability (14,608 pieces versus 672 pieces). This ensures regulatory compliance and supply chain continuity.

Q: Can these terminals be used with wire gauges outside the 14-16 AWG range?

A: No. Both 52957 and 52957-1 are specified exclusively for 14-16 AWG wire. The insulation diameter range (0.118" ~ 0.193" / 3.00mm ~ 4.90mm) and crimp termination design are calibrated for this wire gauge range only.

Q: What is the stud size compatibility?

A: Both parts feature a 10 stud configuration. This stud size is compatible with standard #10 connection points and tab receptacles designed for 10 stud terminals.
