Key Parameters

Substitute Part Grouping Explanation

Substitute part 5-146256-4 (TE Connectivity AMP Connectors) qualifies as an equivalent based on the following critical parameters:

• Identical mating pitch: 0.100" (2.54mm)
• Identical position count and row configuration: 8 positions, 2 rows
• Identical row spacing: 0.100" (2.54mm)
• Matching connector type classification: Header with male pin contacts
• Identical mounting method: Through hole with solder termination
• Matching fastening mechanism: Push-pull
• Identical contact finish specification: Gold mating surface with tin post finish
• Equivalent insulation material category: Both PBT and LCP meet UL94 V-0 flammability requirements
• Matching product status: Active
• Equivalent compliance: Both ROHS3 compliant with MSL 1

Mechanical variations within acceptable tolerance include contact length post (0.115" vs 0.120"), overall contact length (0.445" vs 0.440"), and insulation height (0.100" vs 0.090"). These dimensional differences do not affect functional interchangeability in standard through-hole PCB applications.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-104-23-F-D and 5-146256-4 maintain Active product status and satisfy ROHS3 compliance requirements with UL94 V-0 flammability certification. The TSW-104-23-F-D operates across a wider temperature range (-55°C to 125°C) compared to the TE Connectivity substitute (-65°C to 105°C). Selection between these parts depends on application temperature requirements. The TE Connectivity part features a breakaway connector option and includes a specified current rating of 3A, providing additional design flexibility for certain applications. Both parts are MSL 1 rated, eliminating moisture sensitivity concerns for standard storage and handling conditions.

Frequently Asked Questions (FAQ)

Q: Can the 5-146256-4 directly replace the TSW-104-23-F-D in existing designs?

A: Yes, for applications operating within the overlapping temperature range of -55°C to 105°C. The critical parameters—pitch, position count, row configuration, contact type, mounting method, and termination—are identical. Mechanical dimensional variations are within acceptable tolerance for standard through-hole PCB applications.

Q: What is the difference between the insulation materials used in these connectors?

A: The TSW-104-23-F-D uses Polybutylene Terephthalate (PBT), while the 5-146256-4 uses Liquid Crystal Polymer (LCP). Both materials meet UL94 V-0 flammability requirements. LCP offers superior dimensional stability and lower moisture absorption, while PBT provides established reliability in standard applications.

Q: Are there packaging differences between these parts?

A: Yes. The TSW-104-23-F-D is supplied in Bag packaging, while the 5-146256-4 is supplied in Bulk packaging. This affects inventory management and handling procedures but does not impact electrical or mechanical performance.

Q: What is the significance of the breakaway feature on the TE Connectivity part?

A: The breakaway feature on the 5-146256-4 allows individual connector positions to be separated after assembly, providing design flexibility for applications requiring modular connector configurations. The TSW-104-23-F-D does not include this feature.

Q: How do the operating temperature ranges compare?

A: The TSW-104-23-F-D operates from -55°C to 125°C, while the 5-146256-4 operates from -65°C to 105°C. The Samtec part supports higher maximum temperatures; the TE Connectivity part supports lower minimum temperatures. Application requirements determine which range is appropriate.

Q: Are both parts RoHS compliant?

A: Yes, both the TSW-104-23-F-D and 5-146256-4 are ROHS3 compliant. The TE Connectivity part additionally carries REACH Unaffected status.
