Molex 0022284047 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0022284047 is a through-hole rectangular connector header with 4 positions at 0.100" (2.54mm) pitch, designed for board-to-board or cable applications. This unshrouded, breakaway header features gold-plated mating contacts and tin-plated posts, with solder termination and push-pull fastening. The connector is constructed from glass-filled polyamide insulation and is rated UL94 V-0 for flammability. The part is currently active in production with 730 units in stock.

Equivalent and substitute parts are necessary when the original Molex part is unavailable, when alternative sourcing reduces lead times or costs, or when design requirements allow for compatible alternatives from other manufacturers that meet the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the Molex 0022284047 is determined by strict adherence to the following critical parameters:

Primary Matching Criteria:

Number of positions: 4
Pitch - mating: 0.100" (2.54mm)
Connector type: Header, Breakaway
Contact type: Male Pin
Mounting type: Through Hole
Termination: Solder
Fastening type: Push-Pull
Shrouding: Unshrouded
Number of rows: 1

Secondary Compatibility Parameters:

Contact finish - mating: Gold or Tin (both acceptable for 2.54mm pitch headers)
Insulation material: Polyamide, Polybutylene Terephthalate (PBT), or Polycyclohexylenedimethylene Terephthalate (PCT)
Material flammability rating: UL94 V-0
RoHS compliance status: ROHS3 Compliant or RoHS Compliant

All substitute parts listed meet these criteria. Variations in contact length, insulation height, and contact finish thickness do not prevent substitution when the primary and secondary parameters align.

Engineering Selection Recommendations

Preferred Substitutes (ROHS3 Compliant, Active Status):

TE Connectivity 826629-4 and 826646-4 are direct functional equivalents with ROHS3 compliance and active product status. Both feature gold-plated mating contacts, PBT insulation, and UL94 V-0 rating. The 826629-4 offers the highest inventory availability (471,384 units) and is recommended as the primary substitute. The 826646-4 differs only in contact length specifications and remains fully compatible.

TE Connectivity 826926-4 is functionally equivalent with tin-plated mating contacts instead of gold. This part maintains ROHS3 compliance, UL94 V-0 rating, and active status. Tin plating is acceptable for 2.54mm pitch applications and does not compromise electrical performance.

3M 929834-01-04-RK and 929834-04-04-RK are RoHS-compliant alternatives with tin-plated contacts and PCT insulation. Both maintain UL94 V-0 rating and active product status. The primary difference between these parts is contact post length (0.110" versus 0.510"), which affects board-to-board stacking height but does not prevent substitution for standard applications.

Secondary Substitutes (RoHS Compliant, Active Status):

3M 929647-01-04-I and 929647-09-04-I feature gold-plated mating contacts and PBT insulation with glass filler. Both are RoHS compliant and UL94 V-0 rated. These parts differ in contact post length (0.110" versus 0.145") and are suitable for applications where gold plating is required.

3M 929400-01-04-RK is a tin-plated alternative with PCT insulation and UL94 V-0 rating. RoHS compliance status is not specified in the data provided.

Not Recommended:

3M 929834-01-04 is RoHS non-compliant and REACH-affected due to tin-lead plating. This part should not be selected for new designs or applications requiring RoHS compliance.

Mill-Max 334-10-104-00-010000 features extended posts and differs in contact type classification. While mechanically compatible, this part is not a direct functional equivalent and should be evaluated separately for specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute a tin-plated contact header for the gold-plated Molex 0022284047?

A: Yes. Both tin and gold plating are acceptable contact finishes for 2.54mm pitch rectangular connectors. Tin-plated alternatives such as TE Connectivity 826926-4 or 3M 929834-01-04-RK provide equivalent electrical performance and are fully compatible. Contact finish selection depends on application-specific corrosion resistance requirements rather than mechanical compatibility.

Q: What is the difference between the 3M 929834-01-04-RK and 929834-04-04-RK?

A: Both parts are identical except for contact post length. The 929834-01-04-RK has 0.110" posts, while the 929834-04-04-RK has 0.510" posts. Post length affects the overall connector height and board-to-board stacking distance. Select based on your PCB thickness and mating connector requirements. Both are electrically and mechanically equivalent to the Molex 0022284047.

Q: Are all listed substitutes RoHS compliant?

A: Most substitutes are ROHS3 or RoHS compliant. The exception is 3M 929834-01-04, which uses tin-lead plating and is RoHS non-compliant. For applications requiring RoHS compliance, select from TE Connectivity (826629-4, 826646-4, 826926-4), 3M RoHS-compliant variants (929834-01-04-RK, 929834-04-04-RK, 929647-01-04-I, 929647-09-04-I), or Mill-Max 334-10-104-00-010000.

Q: Does insulation material affect substitution compatibility?

A: No. The Molex 0022284047 uses polyamide insulation, while substitutes use PBT or PCT. All three materials meet UL94 V-0 flammability requirements and are suitable for the same applications. Material selection does not prevent substitution when all other parameters match.

Q: What is the difference between the TE Connectivity 826629-4 and 826646-4?

A: Both parts are from the AMPMODU Mod II series with identical electrical specifications. The primary difference is contact length for mating: 826629-4 has 0.264" (6.70mm) mating contact length, while 826646-4 has 0.228" (5.80mm). This affects engagement depth with mating connectors. Select based on your specific mating connector requirements. Both are fully compatible with the Molex 0022284047 for standard applications.

Q: Can I use the Mill-Max 334-10-104-00-010000 as a direct substitute?

A: The Mill-Max part is mechanically compatible but differs in contact type classification (Post, Extended versus Male Pin). While it maintains the same pitch, position count, and mounting method, it is not a direct functional equivalent. Evaluate this part separately for your specific application requirements before selection.

Q: Which substitute offers the best inventory availability?

A: TE Connectivity 826629-4 has the highest inventory with 471,384 units in stock, followed by 3M 929834-01-04-RK with 8,501 units. For immediate availability, these are the recommended choices.
