Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ESZH02160 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• Position Count and Pitch: All substitutes maintain 2 positions with 0.197" (5.00mm) pitch spacing, ensuring PCB layout compatibility.
• Mounting Configuration: All substitutes feature vertical through-hole mounting with identical contact tail length (0.138" / 4.60mm) and insulation height (0.079" / 2.00mm).
• Electrical Ratings: All substitutes meet or exceed the UL voltage rating of 300 V. Current ratings range from 12 A to 16 A, all suitable for the specified application.
• Termination Method: All substitutes use solder termination compatible with standard PCB assembly processes.
• Compliance: All substitutes maintain RoHS3 compliance or equivalent environmental standards.

The three identified substitutes—1546931-2 (TE Connectivity), 1933189 (Phoenix Contact), and OSTOP020000 (On Shore Technology)—meet these core substitution criteria and are available in production quantities.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Direct Equivalents)

1546931-2 (TE Connectivity AMP Connectors) and 1933189 (Phoenix Contact COMBICON PST) are the primary substitutes for ESZH02160. Both maintain identical pitch, position count, mounting orientation, and contact dimensions. TE Connectivity 1546931-2 matches the original 12 A current rating, while Phoenix Contact 1933189 provides enhanced current capacity at 16 A UL rating. Both are ROHS3 compliant with unlimited moisture sensitivity rating.

Secondary Substitute (Dimensional Variance)

OSTOP020000 (On Shore Technology OSTOP series) qualifies as a functional substitute with one notable dimensional difference: insulation height is 0.138" (4.60mm) versus the standard 0.079" (2.00mm). This increased insulation height may affect PCB clearance and component spacing. OSTOP020000 maintains the required 300 V voltage rating and tin contact finish. ROHS3 compliance is confirmed.

Compliance and Availability

All three substitutes carry active product status and ROHS3 compliance certification. Inventory availability is substantial: 1546931-2 (2,120 pcs), 1933189 (5,861 pcs), and OSTOP020000 (864 pcs). Selection should prioritize dimensional compatibility with existing PCB layouts and mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can 1546931-2 be used as a direct replacement for ESZH02160?

A: Yes. Both parts share identical specifications for position count (2), pitch (5.00mm), mounting type (vertical through-hole), contact tail length (4.60mm), insulation height (2.00mm), and UL voltage rating (300 V). Current rating is identical at 12 A. Packaging differs (tray vs. bulk), but electrical and mechanical compatibility is confirmed.

Q: What is the key difference between 1933189 and ESZH02160?

A: The primary difference is current rating: 1933189 is rated for 16 A (UL) compared to 12 A for ESZH02160. Additionally, 1933189 provides IEC current rating of 12 A and IEC voltage rating of 400 V, offering broader compliance coverage. All other critical parameters—pitch, position count, mounting configuration, and contact dimensions—are identical.

Q: Why does OSTOP020000 have a different insulation height?

A: OSTOP020000 specifies insulation height of 0.138" (4.60mm) versus the standard 0.079" (2.00mm) for other substitutes. This dimensional variance may impact PCB layout compatibility and component spacing. Verify clearance requirements before selection.

Q: Are all substitutes RoHS compliant?

A: Yes. ESZH02160 is RoHS compliant. All three substitutes carry ROHS3 compliance certification, meeting current environmental standards.

Q: What packaging formats are available?

A: ESZH02160 is supplied in tray packaging. Substitutes 1546931-2, 1933189, and OSTOP020000 are supplied in bulk packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: Do all substitutes use tin contact finish?

A: Yes. All four parts—ESZH02160, 1546931-2, 1933189, and OSTOP020000—specify tin contact mating finish, ensuring consistent soldering characteristics and contact reliability.
