Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RLR07C1001FRM22 is determined by strict equivalence across the following parameters:

• Resistance value: 1 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Package: Axial
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C to 150°C
• Physical dimensions: 0.090" Dia x 0.250" L
• Series compliance: MIL-PRF-39017/01, RLR07
• Military-grade features: Moisture resistant, weldable

The RLR07C1001FRB14 meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical specifications, mechanical dimensions, and military certifications, making them interchangeable in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both RLR07C1001FRM22 and RLR07C1001FRB14 are active production parts manufactured by Vishay Dale under identical military specifications. Selection between these parts should be based on inventory availability and procurement lead times. The RLR07C1001FRB14 offers higher stock availability (1052 units versus 673 units), which may reduce procurement delays in high-volume applications.

Both parts carry identical compliance status: RoHS non-compliant, REACH affected, and ECCN EAR99 classification. No compliance or certification advantage exists between the two options. For applications requiring military-grade reliability, moisture resistance, and weldability, either part satisfies the requirement without performance differentiation.

Frequently Asked Questions (FAQ)

Q: Are RLR07C1001FRM22 and RLR07C1001FRB14 electrically identical?

A: Yes. Both parts have identical resistance value (1 kOhms), tolerance (±1%), power rating (0.25W), temperature coefficient (±100ppm/°C), and operating temperature range (-65°C to 150°C). They are electrically interchangeable.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Both parts share identical axial package dimensions (0.090" Dia x 0.250" L), termination count (2), and through-hole mounting specifications. No PCB layout modifications are required when substituting between these parts.

Q: Do both parts meet military specifications?

A: Yes. Both RLR07C1001FRM22 and RLR07C1001FRB14 comply with MIL-PRF-39017/01 and belong to the RLR07 military-grade series. Both feature moisture resistance and weldability as specified for military applications.

Q: What is the difference between these part numbers?

A: The part numbers differ only in their suffix designations (FRM22 versus FRB14). These designations reflect internal Vishay Dale manufacturing or packaging batch codes. All electrical, mechanical, and performance specifications are identical.

Q: Which part should I select for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability and supplier lead times. The RLR07C1001FRB14 currently has higher stock availability.
