Parameter Comparison

Engineering Selection Recommendations

The substitute part 7-1415899-7 is the manufacturer-recommended equivalent for the obsolete 2-2158100-2. Selection of this substitute is based on the following engineering factors:

Electrical Equivalence: All critical electrical parameters are identical, including contact form, current rating, coil voltage, switching voltage, and timing characteristics. The substitute exhibits lower coil current (33.3 mA versus 44.1 mA) and higher coil resistance (360 Ohms versus 272 Ohms), both of which are compatible with the original design requirements.

Mechanical Compatibility: Through-hole mounting, PC pin termination, and sealed flux protection are maintained. Physical compatibility with existing PCB layouts is preserved.

Environmental Performance: The substitute provides an extended operating temperature range (-40°C to 85°C versus -40°C to 70°C), offering improved thermal margin for industrial applications.

Compliance & Availability: The substitute maintains ROHS3 compliance and MSL 1 rating. Active product status ensures long-term supply chain availability and technical support from TE Connectivity Potter & Brumfield Relays.

Packaging Consideration: The substitute is supplied in tube packaging, whereas the original part number does not specify packaging format. Tube packaging is standard for through-hole relay distribution and is compatible with automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 7-1415899-7 be used as a direct replacement for the 2-2158100-2 in existing designs?

A: Yes. The 7-1415899-7 meets all critical electrical and mechanical specifications required for direct substitution. Contact form, current rating, coil voltage, switching voltage, timing, and termination style are identical. The substitute is the manufacturer-recommended equivalent.

Q: What is the significance of the lower coil current in the substitute part?

A: The substitute part draws 33.3 mA compared to 44.1 mA in the original. This reduction results from higher coil resistance (360 Ohms versus 272 Ohms) while maintaining the same 12VDC coil voltage. Both designs meet the same must-operate and must-release voltage thresholds. Lower coil current reduces power consumption and heat generation, which is beneficial for circuit design.

Q: Does the extended temperature range of the substitute affect compatibility?

A: No. The substitute operates from -40°C to 85°C, compared to -40°C to 70°C for the original. The extended upper temperature limit provides additional thermal margin and does not compromise compatibility with applications designed for the original temperature range.

Q: Are there packaging differences between the two parts?

A: The original part number does not specify packaging format. The substitute is supplied in tube packaging, which is standard for through-hole relay distribution and is compatible with both manual and automated assembly processes.

Q: Is the substitute part RoHS compliant?

A: Yes. The 7-1415899-7 is ROHS3 compliant and maintains MSL 1 (unlimited) moisture sensitivity level, matching the compliance profile of the original part.

Q: Why is the original part classified as obsolete?

A: The 2-2158100-2 is obsolete due to product lifecycle management by TE Connectivity. The 7-1415899-7 is the active replacement that provides equivalent functionality with improved availability and extended environmental performance.

Q: Can the substitute be used in high-frequency switching applications?

A: Both the original and substitute parts have identical operate and release times (8 ms and 6 ms respectively). Switching frequency capability is determined by these timing characteristics and is equivalent between the two parts.
