Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 52951 spade terminal is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 52951-1 maintains identical specifications for terminal type, stud size, wire gauge range, insulation material, contact material, contact finish, and all dimensional characteristics including width, length, insulation diameter, and tongue opening. Both parts are manufactured by TE Connectivity AMP Connectors within the Plasti-Grip series and employ identical crimp termination methodology with serrated termination features.

The primary distinction between these parts is packaging format: the main part number 52951 is supplied in bulk packaging, while the substitute 52951-1 is supplied in cut tape (CT) packaging. This packaging difference does not affect electrical performance, mechanical compatibility, or functional application. Both parts are classified as active products with unlimited moisture sensitivity level (MSL 1).

Parameter Comparison

Engineering Selection Recommendations

Both the 52951 and 52951-1 are functionally equivalent spade terminal connectors suitable for identical applications requiring 16-22 AWG crimp termination on 10 stud connections. Selection between these parts should be based on packaging requirements and compliance specifications.

The 52951 in bulk packaging is appropriate for high-volume manufacturing operations and applications where individual component packaging is not a constraint. The 52951-1 in cut tape packaging is suitable for automated assembly processes, lower-volume applications, and situations where individual component handling and tape-based dispensing are required.

The 52951-1 carries RoHS Compliant certification, while the 52951 is marked as not applicable for RoHS status. For applications subject to RoHS compliance requirements, the 52951-1 is the appropriate selection. Both parts carry identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications and are classified as active products with unlimited moisture sensitivity level.

Frequently Asked Questions (FAQ)

Q: Are the 52951 and 52951-1 electrically identical?

A: Yes. Both parts are manufactured by TE Connectivity AMP Connectors with identical contact material (brass), contact finish (tin), wire gauge range (16-22 AWG), and termination methodology (crimp with serrated termination). Electrical performance is equivalent.

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 high-volume operations. Cut tape packaging supplies components on individual tape segments, suitable for automated pick-and-place assembly equipment and lower-volume applications. The components themselves are identical.

Q: Can I use 52951-1 as a direct replacement for 52951?

A: Yes, the 52951-1 is a direct functional equivalent. All electrical and mechanical parameters are identical. The only differences are packaging format and RoHS compliance status. Selection depends on your assembly process requirements and regulatory compliance needs.

Q: Which part should I specify for RoHS-compliant applications?

A: The 52951-1 carries RoHS Compliant certification. For applications requiring RoHS compliance, specify 52951-1. The 52951 is marked as not applicable for RoHS status.

Q: Are the dimensional specifications identical between these parts?

A: Yes. Both parts have identical overall length (0.920"), width (0.406"), insulation diameter (0.105" ~ 0.140"), tongue inside opening (0.190"), and all other dimensional parameters. They are mechanically interchangeable.

Q: What wire gauge range do these terminals accommodate?

A: Both the 52951 and 52951-1 accommodate 16-22 AWG wire with an insulation diameter range of 0.105" to 0.140" (2.67mm to 3.56mm).

Q: Are both parts currently in production?

A: Yes. Both the 52951 and 52951-1 are classified as active products. The 52951 has 911 pieces in stock, and the 52951-1 has 6193 pieces in stock.
