Engineering Selection Recommendations

All three parts—S7B-EH, 25SH-C-07-TR, and 440053-7—maintain active product status and full ROHS3 compliance. Selection between these rectangular connectors should be based on the following factors:

S7B-EH (JST Sales America Inc.): Primary specification with latch lock fastening and press-fit termination. Suitable for applications requiring positive mechanical retention.

25SH-C-07-TR (Adam Tech): Equivalent substitute with friction lock fastening and kinked pin termination. Features 4-wall shrouding compared to 3-wall on the primary part. White insulation color distinguishes this variant. Appropriate for applications where friction lock engagement is acceptable.

440053-7 (TE Connectivity AMP Connectors): Equivalent substitute with friction lock fastening and press-fit termination. Maintains 3-wall shrouding matching the primary part. Highest inventory availability (17,505 pcs) among the three options. Suitable for general purpose, industrial, automotive, and medical applications.

All parts operate within identical electrical and thermal specifications (3A, 250V, -25°C ~ 85°C) and share the same pitch, position count, and insulation material composition.

Frequently Asked Questions (FAQ)

Q: Can 25SH-C-07-TR replace S7B-EH in existing designs?

A: Yes. Both connectors share identical mating pitch (0.098" / 2.50mm), position count (7), electrical ratings (3A / 250V), and operating temperature range (-25°C ~ 85°C). The primary differences are fastening type (friction lock vs. latch lock), termination method (kinked pin vs. press-fit), and shrouding configuration (4-wall vs. 3-wall). PCB layout compatibility is maintained.

Q: What is the difference between latch lock and friction lock fastening?

A: Latch lock (S7B-EH) provides positive mechanical retention through a locking mechanism. Friction lock (25SH-C-07-TR, 440053-7) relies on contact pressure for retention. Both are suitable for board-to-cable/wire applications; selection depends on application requirements for mating force and unmating security.

Q: Are all three parts RoHS compliant?

A: Yes. S7B-EH, 25SH-C-07-TR, and 440053-7 are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: Does insulation color affect electrical performance?

A: No. Insulation color (Natural vs. White) is a visual identifier only and does not affect electrical or mechanical performance. Both colors indicate identical Polyamide (PA66), Nylon 6/6 material composition.

Q: What is the difference between press-fit and kinked pin termination?

A: Press-fit termination (S7B-EH, 440053-7) uses straight pins inserted into plated through-holes under controlled force. Kinked pin termination (25SH-C-07-TR) uses bent pins for through-hole insertion. Both methods provide solder-compatible connections; selection depends on PCB design and assembly equipment capability.

Q: Which part has the best inventory availability?

A: 440053-7 (TE Connectivity) has the highest inventory at 17,505 pcs, followed by 25SH-C-07-TR (Adam Tech) at 2,869 pcs, and S7B-EH (JST) at 994 pcs.
