CFN-25JR-52-12K Equivalent & Substitute Parts

Part Overview

The CFN-25JR-52-12K is a 12 kOhms ±5% 0.25W through-hole resistor manufactured by YAGEO in axial carbon film composition. This part is classified as obsolete, making equivalent substitutes necessary for ongoing design support and procurement. The CFN series has been superseded by active production alternatives that maintain identical electrical and mechanical specifications while offering improved availability and compliance status.

Substitute Part Grouping Explanation

Substitution eligibility for the CFN-25JR-52-12K is determined by strict equivalence across the following parameters: resistance value (12 kOhms), tolerance (±5%), power rating (0.25W), composition (carbon film), temperature coefficient (-500/+350 ppm/°C), operating temperature range (-55°C to 155°C), and axial package configuration.

The substitute parts are grouped into two categories:

Parametric Equivalents (YAGEO CFR Series): CFR-25JR-52-12K, CFR-25JR-PN12K, and CFR-25JT-52-12K maintain all electrical and mechanical specifications of the original part. These are direct replacements differing only in packaging format (Cut Tape or Tape & Reel) and product status (Active). All three are ROHS3 compliant and currently in active production.

Manufacturer Recommended Equivalent (Stackpole Electronics HDM Series): HDM14JT12K0 meets all core electrical parameters and maintains the moisture-resistant feature of the original CFN part. This substitute differs in physical dimensions (0.071" Dia x 0.126" L versus 0.094" Dia x 0.248" L) while retaining identical electrical performance and axial termination configuration.

Engineering Selection Recommendations

For applications requiring direct form-factor compatibility with existing PCB layouts, the YAGEO CFR series substitutes (CFR-25JR-52-12K, CFR-25JR-PN12K, CFR-25JT-52-12K) are preferred. All three maintain identical dimensions to the original CFN-25JR-52-12K and are in active production with ROHS3 compliance certification. Selection among these three variants depends on procurement packaging requirements: Cut Tape for lower-volume applications or Tape & Reel for automated assembly processes.

The Stackpole Electronics HDM14JT12K0 is suitable for applications where PCB layout constraints permit the smaller physical dimensions (0.071" Dia x 0.126" L). This substitute retains the moisture-resistant feature of the original part and is ROHS3 compliant. The reduced size may provide benefits in space-constrained designs while maintaining full electrical equivalence.

All substitute parts satisfy REACH and ECCN requirements identical to the original specification.

Frequently Asked Questions (FAQ)

Q: Can CFR-25JR-52-12K be used as a direct replacement for CFN-25JR-52-12K?

A: Yes. The CFR-25JR-52-12K is a parametric equivalent with identical resistance (12 kOhms), tolerance (±5%), power rating (0.25W), temperature coefficient (-500/+350 ppm/°C), operating temperature range (-55°C to 155°C), and physical dimensions (0.094" Dia x 0.248" L). The primary difference is product status (Active versus Obsolete) and packaging format (Cut Tape versus bulk).

Q: What is the difference between CFR-25JR-52-12K, CFR-25JR-PN12K, and CFR-25JT-52-12K?

A: All three are YAGEO CFR series resistors with identical electrical specifications and physical dimensions. The differences are packaging format (Cut Tape or Tape & Reel) and inventory availability. Selection depends on procurement and assembly requirements.

Q: Can HDM14JT12K0 be used in place of CFN-25JR-52-12K?

A: HDM14JT12K0 is electrically equivalent with identical resistance, tolerance, power rating, and temperature characteristics. However, it has smaller physical dimensions (0.071" Dia x 0.126" L versus 0.094" Dia x 0.248" L). Substitution is valid only if PCB layout and mechanical constraints accommodate the reduced size.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. CFR-25JR-52-12K, CFR-25JR-PN12K, CFR-25JT-52-12K, and HDM14JT12K0 are all ROHS3 compliant. The original CFN-25JR-52-12K compliance status was not specified in available documentation.

Q: What is the moisture-resistant feature difference between CFN and CFR series?

A: The CFN-25JR-52-12K is specified as moisture resistant. The CFR series substitutes do not list this feature in their specifications. The HDM14JT12K0 retains the moisture-resistant designation. For applications requiring moisture resistance, HDM14JT12K0 is the recommended substitute.

Q: Which substitute has the best inventory availability?

A: CFR-25JR-52-12K has the highest inventory (10297 Pcs), followed by CFR-25JT-52-12K (4797 Pcs), HDM14JT12K0 (832 Pcs), and CFR-25JR-PN12K (640 Pcs).
