Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-101-14-F-D is determined by the following critical parameters:

• Number of positions and rows (2 positions, 2 rows)
• Row spacing of 0.100" (2.54mm)
• Through-hole mounting with solder termination
• Push-pull fastening mechanism
• Square contact shape with gold mating finish
• Unshrouded header configuration
• UL94 V-0 flammability rating

The substitute parts 4-102973-0-01 and 5-146252-1 from TE Connectivity AMP Connectors series AMPMODU Mod II satisfy these core parameters. Both maintain identical position count, row spacing, mounting type, termination method, fastening type, contact geometry, and flammability compliance.

Parameter Comparison

Engineering Selection Recommendations

5-146252-1 (TE Connectivity) is the preferred substitute for new designs and ongoing production. This part maintains active product status, RoHS compliance matching the original TSW-101-14-F-D, and the highest inventory availability at 41,534 units. The insulation material differs (LCP versus PBT), but both materials meet UL94 V-0 flammability requirements. The operating temperature range is narrower (-65°C to 105°C versus -55°C to 125°C), which must be evaluated against specific application requirements.

4-102973-0-01 (TE Connectivity) is not recommended for new designs due to obsolete product status and RoHS non-compliance. This part is suitable only for legacy system maintenance or repair where the original specification cannot be altered. The contact finish post uses Tin-Lead, which introduces additional compliance considerations in regulated environments.

Both substitute parts feature identical mechanical dimensions, contact geometry, and fastening mechanisms, ensuring physical and electrical compatibility within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can 5-146252-1 be used as a direct replacement for TSW-101-14-F-D in new designs?

A: Yes, within the constraints of the operating temperature range. The 5-146252-1 operates from -65°C to 105°C, which is narrower than the TSW-101-14-F-D range of -55°C to 125°C. Verify that your application does not require operation below -65°C or above 105°C.

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

A: The TSW-101-14-F-D uses Polybutylene Terephthalate (PBT), while the 5-146252-1 uses Liquid Crystal Polymer (LCP). Both materials meet UL94 V-0 flammability requirements. LCP offers superior dimensional stability and lower moisture absorption compared to PBT.

Q: Why is 4-102973-0-01 marked as obsolete?

A: The 4-102973-0-01 has been discontinued by TE Connectivity. While inventory remains available, this part should not be specified for new designs. Use 5-146252-1 for active product support.

Q: Are there compliance differences between these parts?

A: The TSW-101-14-F-D and 5-146252-1 are both RoHS compliant. The 4-102973-0-01 is RoHS non-compliant and uses Tin-Lead post finish, which may restrict use in regulated applications.

Q: Do these parts have the same contact dimensions?

A: Contact length dimensions vary slightly. The TSW-101-14-F-D has a mating contact length of 0.320" (8.13mm), while both TE Connectivity substitutes have 0.318" (8.08mm). Post lengths differ: TSW-101-14-F-D is 0.110" (2.79mm) versus 0.125" (3.18mm) for the substitutes. These minor variations remain within typical manufacturing tolerances for this connector class.

Q: What is the current rating for these connectors?

A: The TSW-101-14-F-D does not specify a current rating in the provided data. Both TE Connectivity substitutes are rated for 3A per position.
