Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers is determined by alignment of critical electrical and mechanical parameters. The following parameters establish substitution validity:

Primary Substitution Criteria:

• Number of positions (10 positions required)
• Pitch - mating distance (0.100" / 2.54mm required)
• Mounting type (through hole, right angle required)
• Contact type (male pin required)
• Contact shape (square required)
• Termination method (solder required)
• Material flammability rating (UL94 V-0 required)
• RoHS compliance status

Secondary Compatibility Factors:

• Operating temperature range (minimum -40°C acceptable; maximum 105°C acceptable)
• Contact finish material (tin or gold acceptable)
• Insulation material (thermoplastic or polyester variants acceptable)
• Connector style (board-to-cable/wire or board-to-board acceptable)

The three substitute parts listed (929550-01-10-I, 929500-01-10-RK, 929550-01-10-EU) satisfy all primary substitution criteria and operate within acceptable secondary compatibility parameters.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and full RoHS compliance, ensuring regulatory alignment with the primary part 4-644694-0. The three 3M alternatives (929550-01-10-I, 929500-01-10-RK, 929550-01-10-EU) satisfy core electrical and mechanical substitution criteria.

929500-01-10-RK (3M 929 Series): This substitute features tin contact finish matching the primary part specification. Operating temperature range extends to -40°C minimum, which is acceptable for applications not requiring the extended -55°C lower limit of the primary part. Current rating is specified at 2.5A. Fastening type is push-pull, distinguishing this variant for applications requiring positive engagement.

929550-01-10-EU (3M 929 Series): This substitute provides gold contact finish, offering enhanced corrosion resistance compared to the tin-finished primary part. Operating temperature range is -40°C to 105°C. Current rating is 2.5A. Insulation material is PCT, and fastening type is push-pull.

929550-01-10-I (3M 929 Series): This substitute also features gold contact finish with identical electrical specifications to 929550-01-10-EU. Insulation material is glass-filled PBT polyester, providing enhanced mechanical properties. Operating temperature range is -40°C to 105°C with 2.5A current rating and push-pull fastening.

Selection between substitute parts depends on application requirements for contact finish (tin versus gold), insulation material composition, and minimum operating temperature threshold. All three substitutes are suitable for general-purpose rectangular connector applications requiring 10-position, 2.54mm pitch through-hole right-angle headers.

Frequently Asked Questions (FAQ)

Q: Can the 3M 929 series headers substitute for the TE Connectivity MTA-100 4-644694-0 in all applications?

A: The 3M 929 series headers satisfy core electrical and mechanical substitution criteria including 10 positions, 0.100" pitch, through-hole right-angle mounting, male pin contacts, square contact shape, and solder termination. However, the operating temperature minimum differs: the primary part operates from -55°C while 3M substitutes operate from -40°C. Applications requiring operation below -40°C require the primary part. All other electrical and mechanical parameters align within acceptable tolerances.

Q: What is the difference between the three 3M substitute parts?

A: The primary differences are contact finish and insulation material. Part 929500-01-10-RK features tin contact finish identical to the primary part. Parts 929550-01-10-EU and 929550-01-10-I both feature gold contact finish for enhanced corrosion resistance. Insulation material differs between 929550-01-10-EU (PCT) and 929550-01-10-I (glass-filled PBT polyester). All three share identical electrical specifications: 2.5A current rating, -40°C to 105°C operating range, and push-pull fastening.

Q: Are there voltage rating differences between the primary part and substitutes?

A: The primary part 4-644694-0 specifies 250VAC voltage rating. The 3M substitute parts do not list voltage rating in their specifications. Applications requiring explicit voltage rating specification should verify 3M part voltage capabilities through manufacturer documentation before substitution.

Q: What is the significance of the "breakaway" connector type designation on the 3M parts?

A: The 3M 929 series headers are designated as "Header, Breakaway" connectors, indicating the connector positions can be separated into smaller configurations. The primary TE Connectivity part is designated as "Header" without breakaway capability. This distinction does not affect substitution validity for applications using the full 10-position configuration.

Q: Do the substitute parts have different board-to-cable versus board-to-board style implications?

A: The primary part 4-644694-0 is specified for board-to-cable/wire style connections. The 3M substitutes are specified for board-to-board style. Both styles accommodate solder termination to printed circuit boards. The style designation reflects typical application context rather than fundamental electrical or mechanical incompatibility. Substitution is valid for applications using solder termination regardless of style designation.

Q: What is the current rating difference between the primary part and substitutes?

A: The primary part 4-644694-0 specifies current rating as "Varies by Wire Gauge," indicating current capacity depends on the wire gauge of connected conductors. The 3M substitutes specify fixed 2.5A current rating. For applications requiring current capacity determination, consult wire gauge specifications and thermal requirements.

Q: Are all parts RoHS compliant and suitable for regulated industries?

A: All four parts (primary and three substitutes) are RoHS compliant and carry EAR99 ECCN classification with identical HTSUS code 8536.69.4040. All parts carry UL94 V-0 material flammability rating. These specifications ensure regulatory alignment for applications subject to RoHS directives and export control requirements.
