Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connectors in the MTA-156 series is determined by strict equivalence across the following parameters: connector type (receptacle), contact type (female socket), number of positions (12), pitch (0.156"), number of rows (1), cable termination method (IDC), wire gauge (24 AWG), contact finish (tin), and RoHS compliance status. Parts meeting all these criteria are classified as direct substitutes. The substitute part 4-640429-2 satisfies all substitution parameters while offering active product status and improved availability compared to the obsolete main part.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 4-640429-2 is a direct functional equivalent to the obsolete 4-640434-2. Both components share identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch, termination method, wire gauge, and contact finish. The substitute part maintains RoHS compliance and identical moisture sensitivity classification. The primary distinction is product status: 4-640429-2 is active with higher inventory availability (1445 pcs vs. 723 pcs), whereas 4-640434-2 is obsolete. For new designs and ongoing procurement, 4-640429-2 is the appropriate selection. For legacy system repairs requiring exact part matching, 4-640434-2 remains available from current inventory while stock exists.

Frequently Asked Questions (FAQ)

Q: Can 4-640429-2 be used as a direct replacement for 4-640434-2 in existing assemblies?

A: Yes. Both parts are 12-position rectangular receptacle connectors in the MTA-156 series with identical pitch (0.156"), IDC termination, 24 AWG wire gauge, tin contact finish, and closed-end design. Electrical and mechanical compatibility is complete.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and packaging. Part 4-640434-2 is obsolete with 723 pcs in stock, while 4-640429-2 is active with 1445 pcs available in bulk packaging. All functional specifications are identical.

Q: Are there any compatibility concerns when substituting 4-640429-2 for 4-640434-2?

A: No compatibility concerns exist. Both parts conform to identical specifications for connector type, contact configuration, position count, pitch, termination method, wire gauge, contact finish thickness, and RoHS compliance.

Q: Does the packaging difference affect connector performance?

A: Packaging format (bulk vs. standard) does not affect connector electrical or mechanical performance. Packaging is a logistics consideration only.

Q: Are both parts RoHS compliant?

A: Yes. Both 4-640434-2 and 4-640429-2 are RoHS compliant with identical moisture sensitivity level (MSL 1 - Unlimited).

Q: Which part should be specified for new designs?

A: Part 4-640429-2 should be specified for new designs due to active product status and continued manufacturer support. Part 4-640434-2 is obsolete and should be used only for legacy system maintenance where exact part matching is required.
