Substitute Part Grouping Explanation

Substitution eligibility for the RN60D4321FRE6 is determined by strict equivalence across the following critical parameters:

• Resistance value: 4.32 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W/1/4W (exact match required)
• Composition: Metal Film (exact match required)
• Package configuration: Axial (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -65°C to 175°C (exact match required)
• Series: RN60 military-grade classification (exact match required)
• Physical dimensions: 0.145" Dia × 0.344" L (exact match required)

The identified substitute part RN60D4321FB14 maintains complete electrical and mechanical equivalence to the primary part. The sole distinction between these components is packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is supplied in Bulk packaging. Both parts originate from the same manufacturer (Vishay Dale) and base product line (RN60).

Parameter Comparison

Engineering Selection Recommendations

Both RN60D4321FRE6 and RN60D4321FB14 maintain active product status from Vishay Dale and are functionally equivalent for circuit applications requiring 4.32 kOhms ±1% metal film resistors in military-grade specifications. Selection between these parts should be based on procurement and assembly requirements:

RN60D4321FRE6 (Tape & Reel packaging) is appropriate for automated assembly processes and high-volume production environments where component tape feeding systems are utilized.

RN60D4321FB14 (Bulk packaging) is appropriate for manual assembly, low-volume production, or applications where individual component handling is preferred.

Both parts carry identical compliance status: RoHS non-compliant and REACH Affected. Regulatory requirements applicable to the primary part apply equally to the substitute. Current inventory levels (727 units for RN60D4321FRE6 and 1006 units for RN60D4321FB14) support procurement decisions based on delivery timeline and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can RN60D4321FB14 be used as a direct replacement for RN60D4321FRE6 in circuit design?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Bulk versus Tape & Reel). Circuit performance, electrical characteristics, and reliability specifications are equivalent.

Q: What is the significance of the packaging difference between these parts?

A: Packaging format affects handling and assembly methodology. Tape & Reel (TR) packaging is designed for automated pick-and-place assembly systems. Bulk packaging is used for manual assembly or applications where components are handled individually. The resistor component itself is identical in both formats.

Q: Are there any compliance or certification differences between these substitute parts?

A: No. Both parts share identical RoHS status (non-compliant), REACH status (Affected), ECCN classification (EAR99), and HTSUS code (8533.21.0090). Regulatory and compliance considerations apply uniformly to both parts.

Q: What parameters must remain identical for substitution eligibility?

A: Resistance value (4.32 kOhms), tolerance (±1%), power rating (0.25W), composition (Metal Film), temperature coefficient (±100ppm/°C), operating temperature range (-65°C to 175°C), package configuration (Axial), physical dimensions (0.145" Dia × 0.344" L), and military series classification (RN60/MIL-R-10509/1) must all match exactly.

Q: Which part should be selected for high-volume automated assembly?

A: RN60D4321FRE6 in Tape & Reel packaging is optimized for automated assembly processes. This format enables efficient component feeding through pick-and-place equipment.

Q: Which part should be selected for manual assembly or prototyping?

A: RN60D4321FB14 in Bulk packaging is suitable for manual assembly, prototyping, or low-volume applications where individual component handling is standard practice.
