Substitute Part Grouping Explanation

Substitution between TE Connectivity 120789-1 and 5120789-1 is based on electrical and mechanical parameter equivalence. Both parts share identical specifications across all critical functional parameters: 30-position configuration, 0.098" pitch, dual beam left-side style, through-hole right-angle mounting, press-fit termination, 1.15A current rating, 250V voltage rating, -65°C to 105°C operating temperature range, gold contact finish at 30.0µin thickness, and UL94 V-0 flammability rating.

The primary distinction between these parts is packaging format and regulatory compliance status. The 120789-1 is supplied in standard packaging with RoHS non-compliant status, while the 5120789-1 is supplied in tube packaging with ROHS3 compliance. Both parts maintain identical Z-PACK HS3 series designation and active product status. The substitution logic is based on functional equivalence with no electrical or mechanical parameter variation.

Parameter Comparison

Engineering Selection Recommendations

Selection between 120789-1 and 5120789-1 is determined by regulatory compliance requirements and packaging specifications for the end application.

120789-1 Selection Criteria: This part is appropriate for applications where RoHS compliance is not mandated or where legacy system compatibility is required. Standard packaging is suitable for standard component handling and storage procedures.

5120789-1 Selection Criteria: This part is required for applications subject to ROHS3 compliance regulations. Tube packaging provides enhanced protection during transport and storage, making it suitable for applications requiring additional packaging integrity. The ROHS3 compliant status qualifies this part for use in regulated markets and applications with environmental compliance requirements.

Both parts are electrically and mechanically equivalent with identical performance characteristics across all functional parameters. Selection should be based on compliance documentation requirements and packaging specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Are 120789-1 and 5120789-1 electrically interchangeable?

A: Yes. Both parts are electrically identical with matching current ratings (1.15A), voltage ratings (250V), operating temperature ranges (-65°C to 105°C), and contact specifications. They perform identically in circuit applications.

Q: What is the difference between these two part numbers?

A: The primary differences are packaging format and RoHS compliance status. The 120789-1 uses standard packaging and is RoHS non-compliant. The 5120789-1 uses tube packaging and is ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Can I use 5120789-1 as a direct replacement for 120789-1?

A: Yes, 5120789-1 is a direct functional substitute for 120789-1. The tube packaging and ROHS3 compliance of the 5120789-1 make it suitable for applications requiring these specifications. No circuit modifications or design changes are required.

Q: Which part should I specify for new designs?

A: For new designs, specify 5120789-1 if ROHS3 compliance is required by your application or market. Specify 120789-1 only if legacy system compatibility or non-compliant component specifications are explicitly required.

Q: Does packaging affect connector performance?

A: No. Packaging differences do not affect electrical or mechanical performance. Tube packaging provides enhanced protection during handling and storage but does not alter connector functionality or specifications.

Q: Are both parts currently available?

A: Yes. Both parts maintain active product status with current inventory: 120789-1 has 1122 pieces in stock, and 5120789-1 has 1671 pieces in stock.

Q: What is the pitch specification for these connectors?

A: Both parts have a pitch of 0.098" (2.50mm) with 30 positions arranged in 6 rows and 5 columns.

Q: Are these connectors suitable for high-temperature applications?

A: Yes. Both parts are rated for operating temperatures from -65°C to 105°C, making them suitable for standard industrial and commercial temperature ranges.
