Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1-644887-3 is determined by strict alignment with the following core parameters: connector type (header), contact type (male pin), mating pitch (0.100"/2.54mm), number of positions (13), number of rows (1), mounting type (through hole, right angle), contact shape (square), and material flammability rating (UL94 V-0).

The substitute parts identified—3M 929500-01-13, 929500-01-13-RK, 929550-01-13-EU, and 929550-01-13-I—satisfy these core mechanical and electrical compatibility requirements. All substitute parts are 3M 929 series headers with identical pitch, position count, row configuration, and mounting orientation. All maintain UL94 V-0 flammability compliance.

Differences exist in contact finish specifications, insulation material composition, fastening type (push-pull versus kinked pin), and regulatory compliance status. These differences are documented in the parameter comparison table to enable informed selection based on application requirements and compliance constraints.

Parameter Comparison

Engineering Selection Recommendations

For RoHS Compliant Applications:

The 929500-01-13-RK and 929550-01-13-EU are the appropriate selections when RoHS compliance is required. Both parts carry RoHS Compliant status and REACH Unaffected designation. The 929500-01-13-RK features tin contact finish with 200.0µin (5.08µm) thickness and PCT insulation material. The 929550-01-13-EU provides gold contact finish with 10.0µin (0.25µm) thickness and PCT insulation material. Selection between these two depends on contact finish requirements for the specific application.

For Non-RoHS Constrained Applications:

The 929500-01-13 and 929550-01-13-I are suitable for applications without RoHS compliance mandates. The 929500-01-13 carries RoHS non-compliant status with tin-lead contact finish and 100.0µin (2.54µm) thickness. The 929550-01-13-I also carries RoHS non-compliant status with gold contact finish and 10.0µin (0.25µm) thickness.

Temperature Consideration:

The original 1-644887-3 operates across -55°C to 105°C. All substitute parts operate across -40°C to 105°C. Applications requiring operation below -40°C cannot use these substitutes without design modification.

Contact Finish Selection:

Gold-finished contacts (929550-01-13-EU, 929550-01-13-I) provide superior corrosion resistance and are preferred for applications with extended shelf life or exposure to corrosive environments. Tin or tin-lead finished contacts (929500-01-13, 929500-01-13-RK) are suitable for standard industrial applications with standard environmental protection.

Frequently Asked Questions (FAQ)

Q: Can the 3M 929 series headers directly replace the TE Connectivity MTA-100 1-644887-3?

A: The 3M 929 series headers are mechanically and electrically compatible with the 1-644887-3 based on core parameters: identical 0.100" (2.54mm) pitch, 13-position single-row configuration, through-hole right-angle mounting, square contact shape, and UL94 V-0 flammability rating. However, differences in contact finish, insulation material, and operating temperature range exist. Verification of these differences against specific application requirements is necessary before implementation.

Q: What is the primary difference between the 929500-01-13 and 929550-01-13 series?

A: The 929500 series features tin-lead or tin contact finish, while the 929550 series features gold contact finish. Gold-finished contacts provide enhanced corrosion resistance and are typically specified for applications requiring extended reliability or exposure to challenging environmental conditions. Tin and tin-lead finishes are suitable for standard industrial applications.

Q: Are all substitute parts available in the same packaging as the original 1-644887-3?

A: The original 1-644887-3 packaging specification is not provided in the input data. All substitute parts are available in bulk packaging. Specific packaging requirements should be confirmed with the component supplier.

Q: What is the significance of the RoHS compliance difference between substitute parts?

A: RoHS compliance is a regulatory requirement in many jurisdictions, particularly for products sold in the European Union. The 929500-01-13-RK and 929550-01-13-EU are RoHS Compliant and suitable for applications subject to RoHS regulations. The 929500-01-13 and 929550-01-13-I are RoHS non-compliant and are restricted to applications without RoHS compliance mandates.

Q: Does the lower operating temperature minimum of the substitute parts (-40°C versus -55°C) affect compatibility?

A: Applications requiring operation below -40°C cannot use the 3M 929 series substitutes without design modification. The original 1-644887-3 supports operation to -55°C. For applications operating within the -40°C to 105°C range, the substitute parts are compatible.

Q: What is the difference between the 929550-01-13-EU and 929550-01-13-I variants?

A: Both parts feature gold contact finish and identical electrical specifications. The primary difference is insulation material: 929550-01-13-EU uses polycyclohexylenedimethylene terephthalate (PCT), while 929550-01-13-I uses polybutylene terephthalate (PBT) with polyester and glass filler. Material selection depends on specific thermal and mechanical requirements of the application.

Q: Are the substitute parts rated for the same current as the original 1-644887-3?

A: The original 1-644887-3 current rating varies by wire gauge. The substitute parts are rated at 2.5A. Applications requiring current ratings dependent on wire gauge should confirm compatibility with the 2.5A specification of the substitute parts.

Q: What does "breakaway" connector type mean for the 3M 929 series?

A: Breakaway designation indicates that the connector header can be separated into individual pins or smaller groups through mechanical breaking along designed weak points. This feature provides flexibility in connector configuration for applications requiring custom pin arrangements.
