RC14JB22R0 Equivalent & Substitute Parts

Part Overview

The RC14JB22R0 is a 22 Ohm ±5% 1/4W axial through-hole resistor manufactured by Stackpole Electronics Inc. This carbon composition resistor features non-inductive and pulse withstanding characteristics, designed for applications requiring reliable performance across the -55°C to 125°C operating temperature range. The product is currently obsolete, making equivalent substitutes necessary for ongoing system maintenance and new designs requiring compatible specifications.

Substitute Part Grouping Explanation

Substitution of the RC14JB22R0 is based on the following critical parameters:

• Resistance Value: Must be 22 Ohms
• Tolerance: Must be ±5% or tighter
• Package Type: Must be Axial for mechanical compatibility
• Termination Count: Must be 2 terminations
• Compliance: Must maintain ROHS3 compliance and REACH unaffected status

The ASRM12JA22R0 qualifies as a substitute despite composition and power rating differences because it maintains the core electrical specifications (22 Ohms ±5%), axial package configuration, and required compliance certifications. The higher power rating (0.5W vs 0.25W) and metal film composition provide enhanced performance characteristics while preserving functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The ASRM12JA22R0 is the manufacturer-recommended substitute for the obsolete RC14JB22R0. Both components maintain identical resistance values and tolerances, ensuring electrical equivalence in circuit applications. The substitute part is currently in active production status with confirmed inventory availability, addressing the obsolescence of the original part.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component selection. The axial package configuration is identical, ensuring mechanical compatibility with existing PCB layouts and through-hole assembly processes.

The ASRM12JA22R0 provides extended operating temperature range (-55°C to 155°C versus -55°C to 125°C) and higher power dissipation capability (0.5W versus 0.25W), offering improved thermal performance margins in applications where the original part was specified.

Frequently Asked Questions (FAQ)

Q: Can the ASRM12JA22R0 be used as a direct replacement for the RC14JB22R0?

A: Yes. Both components have identical resistance values (22 Ohms) and tolerance specifications (±5%), identical axial package configurations, and equivalent termination counts. The substitute maintains all required compliance certifications.

Q: What are the physical dimension differences between these parts?

A: The RC14JB22R0 measures 0.094" diameter × 0.248" length (2.40mm × 6.30mm). The ASRM12JA22R0 measures 0.118" diameter × 0.354" length (3.00mm × 9.00mm). Both are axial package types suitable for through-hole mounting, though the substitute is slightly larger.

Q: Why does the substitute have a higher power rating?

A: The ASRM12JA22R0 uses metal film composition versus the carbon composition of the RC14JB22R0, resulting in higher power handling capability (0.5W versus 0.25W). This provides additional thermal margin without affecting electrical performance at the specified 22 Ohm resistance value.

Q: Are there compliance or certification differences?

A: Both parts maintain ROHS3 compliance and REACH unaffected status. The substitute includes flame retardant coating and safety features in addition to the pulse withstanding characteristics of the original part.

Q: What is the temperature coefficient difference?

A: The RC14JB22R0 does not specify a temperature coefficient value. The ASRM12JA22R0 specifies 0 to -1800ppm/°C, indicating metal film stability characteristics. The substitute supports an extended operating temperature range of -55°C to 155°C compared to -55°C to 125°C for the original part.
