Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2-2158100-3 with the 7-1415899-9 is based on alignment of the following critical parameters:

Matching Parameters:

• Coil voltage: 24VDC
• Contact form: SPDT (1 Form C)
• Switching voltage: 400VAC maximum
• Mounting type: Through hole
• Termination style: PC pin
• Coil type: Non latching
• Seal rating: Sealed - flux protection
• Contact material: Silver Nickel (AgNi)
• Coil insulation: Class F
• Must operate voltage: 16.8 VDC
• Must release voltage: 2.4 VDC
• Operate time: 8 ms
• Release time: 6 ms
• RoHS3 compliance
• Manufacturer: TE Connectivity Potter & Brumfield Relays

Differing Parameters:

• Contact rating current: 16A (main part) versus 12A (substitute)
• Operating temperature range: -40°C ~ 70°C (main part) versus -40°C ~ 85°C (substitute)
• Coil current: 22.1 mA (main part) versus 16.7 mA (substitute)
• Coil resistance: 1.09 kOhms (main part) versus 1.44 kOhms (substitute)
• Product status: Obsolete (main part) versus Active (substitute)
• Series designation: RZL, SCHRACK (main part) versus RZ, SCHRACK (substitute)

The substitute part 7-1415899-9 is an active product from the same manufacturer family, providing functional equivalence for applications where the 12A contact rating is sufficient for the circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

The 7-1415899-9 serves as an active equivalent for the obsolete 2-2158100-3 based on the following engineering criteria:

Product Status Alignment: The substitute part maintains active product status with TE Connectivity Potter & Brumfield Relays, ensuring continued availability and manufacturer support. The main part's obsolete classification necessitates transition to an active alternative.

Compliance Certification: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for electronic component procurement in regulated industries.

Functional Compatibility: The substitute part preserves all critical relay characteristics including 24VDC coil voltage, SPDT contact configuration, through-hole mounting, PC pin termination, and sealed flux protection design. Timing parameters (8 ms operate, 6 ms release) and voltage thresholds (16.8 VDC must operate, 2.4 VDC must release) remain identical.

Current Rating Consideration: The substitute part is rated for 12A continuous contact current compared to the main part's 16A rating. Selection of the 7-1415899-9 is appropriate for applications where the circuit load current does not exceed 12A. Applications requiring the full 16A rating require alternative sourcing strategies.

Temperature Operating Range: The substitute part extends the upper operating temperature limit to 85°C compared to the main part's 70°C maximum, providing enhanced thermal margin for elevated ambient conditions.

Coil Efficiency: The substitute part operates at reduced coil current (16.7 mA versus 22.1 mA) with increased coil resistance (1.44 kOhms versus 1.09 kOhms), resulting in lower power consumption during relay energization.

Frequently Asked Questions (FAQ)

Q: Can the 7-1415899-9 directly replace the 2-2158100-3 in existing circuit boards?

A: Physical and electrical compatibility is confirmed for through-hole PC pin mounting. The substitute part maintains identical coil voltage, contact form, switching voltage, and timing characteristics. Compatibility depends on circuit load current requirements not exceeding 12A.

Q: What is the primary limitation of the substitute part?

A: The 7-1415899-9 is rated for 12A continuous contact current, compared to the main part's 16A rating. Applications requiring 16A switching capacity require alternative component selection.

Q: Are both parts suitable for the same environmental conditions?

A: Both parts operate across the -40°C to 70°C range. The substitute part extends operation to 85°C maximum, providing additional thermal capability. Both maintain sealed flux protection and identical moisture sensitivity levels.

Q: What is the significance of the different coil resistance values?

A: The substitute part's higher coil resistance (1.44 kOhms versus 1.09 kOhms) results in lower coil current draw (16.7 mA versus 22.1 mA) at identical 24VDC coil voltage. This reduces power consumption and heat generation during relay operation.

Q: Do both parts meet the same regulatory standards?

A: Both parts maintain ROHS3 compliance and REACH unaffected status. Regulatory compliance is equivalent between the main part and substitute.

Q: What packaging differences exist between these parts?

A: The main part 2-2158100-3 is supplied in standard packaging, while the substitute part 7-1415899-9 is supplied in tube packaging. Both maintain identical component specifications and through-hole mounting characteristics.

Q: Why is the main part classified as obsolete?

A: The 2-2158100-3 is designated obsolete by TE Connectivity Potter & Brumfield Relays. The 7-1415899-9 represents the active product line continuation from the same manufacturer, providing functional equivalence for new designs and legacy system updates.
