Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-644885-9 is determined by the following critical parameters that must align across equivalent parts:

Core Matching Parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 19
• Number of Rows: 1
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Contact Shape: Square
• Material Flammability Rating: UL94 V-0

The substitute parts identified (3M 929 series connectors) satisfy these core parameters. However, variations exist in secondary characteristics including contact finish specifications, insulation material composition, operating temperature lower limit, and regulatory compliance status. These variations must be evaluated against specific application requirements.

Engineering Selection Recommendations

929500-01-19-RK (3M) - Preferred Substitute

The 929500-01-19-RK is the recommended substitute for new designs and procurement. This part is active in production status and carries RoHS Compliant certification with REACH Unaffected status, meeting current regulatory requirements. The tin contact finish with 200.0µin thickness provides robust corrosion resistance. The PCT insulation material offers superior thermal and chemical stability compared to standard thermoplastic. The operating temperature range of -40°C to 105°C covers the majority of industrial applications, with the exception of extended low-temperature environments below -40°C.

929550-01-19-EU (3M) - Gold Contact Alternative

The 929550-01-19-EU provides gold-plated mating contacts (10.0µin thickness) matching the original TE Connectivity part's contact finish specification. This part is RoHS Compliant and REACH Unaffected. The gold finish is suitable for low-signal applications and environments requiring enhanced corrosion resistance. The PCT insulation material provides thermal stability equivalent to 929500-01-19-RK.

929500-01-19 (3M) - Cost-Effective Option

The 929500-01-19 offers the lowest cost alternative with tin-lead contact finish. This part is active but carries RoHS non-compliant and REACH Affected designations. Selection of this part requires confirmation that regulatory compliance is not mandated for the application.

929550-01-19-I (3M) - Gold Contact with Glass-Filled Insulation

The 929550-01-19-I combines gold contact finish with glass-filled PBT insulation material. This part is RoHS non-compliant and REACH Unaffected. The glass-filled insulation provides enhanced mechanical strength and dimensional stability.

Critical Design Considerations

All substitute parts exhibit increased contact length (0.295" versus 0.260") and post length (0.130" versus 0.110"), resulting in greater mated stacking height. PCB layout and mating connector cavity depth must be verified for compatibility. The operating temperature lower limit of -40°C in substitute parts represents a 15°C reduction from the original specification; applications requiring operation below -40°C are not suitable for these substitutes.

Frequently Asked Questions (FAQ)

Q: Can 929500-01-19-RK directly replace 1-644885-9 in existing designs?

A: Direct replacement requires verification of three factors: (1) PCB layout accommodation of increased contact post length (0.130" versus 0.110"), (2) mating connector cavity depth compatibility with the longer contact length (0.295" versus 0.260"), and (3) confirmation that the -40°C lower operating temperature limit is acceptable for the application. Mechanical fit must be validated before production implementation.

Q: What is the difference between the 3M 929 series substitute parts?

A: The 929 series substitutes differ in contact finish specification and insulation material. The 929500-01-19 uses tin-lead finish with glass-filled PBT. The 929500-01-19-RK uses tin finish with PCT insulation and carries RoHS Compliant certification. The 929550-01-19-EU and 929550-01-19-I both use gold contact finish; the former uses PCT insulation while the latter uses glass-filled PBT. Contact finish selection depends on signal integrity requirements and environmental exposure.

Q: Are all substitute parts suitable for 250VAC applications?

A: The original TE Connectivity part specifies 250VAC voltage rating. The 3M substitute parts do not provide explicit voltage rating specifications in the available data. Voltage rating verification with 3M technical documentation is required before application in high-voltage circuits.

Q: Which substitute part is recommended for RoHS-compliant designs?

A: Both 929500-01-19-RK and 929550-01-19-EU carry RoHS Compliant certification. The 929500-01-19-RK is recommended for general applications due to its tin contact finish and superior thermal stability. The 929550-01-19-EU is recommended when gold contact finish is required for signal integrity or corrosion resistance in specific environments.

Q: What is the current rating for the substitute parts?

A: All 3M substitute parts specify 2.5A current rating. The original TE Connectivity part specifies current rating as "Varies by Wire Gauge," indicating current capacity is dependent on the mating wire gauge rather than a fixed connector specification. Applications requiring current capacity above 2.5A must be evaluated against the specific wire gauge used in the mating cable assembly.

Q: Are the substitute parts available in bulk packaging?

A: Yes, all identified substitute parts are available in bulk packaging. Inventory levels are: 929500-01-19 (796 pcs), 929500-01-19-RK (1028 pcs), 929550-01-19-EU (861 pcs), and 929550-01-19-I (1063 pcs).

Q: What is the significance of the "Breakaway" connector type designation in the substitute parts?

A: The 3M 929 series connectors are designated as "Header, Breakaway," indicating the connector supports individual position separation. This feature allows removal of individual pins or pin groups from the header assembly. The original TE Connectivity MTA-100 series does not specify this feature. Designs requiring breakaway functionality benefit from this capability; designs not requiring breakaway functionality are unaffected by this designation.
