Key Parameters

Substitute Part Grouping Explanation

Substitution of the RN60D4121FRE6 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part RN60D4121FB14 maintains identical specifications in the following key areas:

Resistance value and tolerance (4.12 kOhms ±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 x 8.74mm), and military series designation (MIL-R-10509/1, RN60). Both parts share identical feature sets including flame retardant coating, military qualification, moisture resistance, and safety rating.

The primary difference between the main part and its substitute is packaging format: the RN60D4121FRE6 is supplied in Tape & Reel configuration, while the RN60D4121FB14 is supplied in Bulk packaging. This distinction affects only procurement and handling methods, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the RN60D4121FRE6 and RN60D4121FB14 are active, production-status components manufactured by Vishay Dale. Selection between these parts is based on procurement requirements and supply chain considerations rather than electrical or mechanical performance differences.

The RN60D4121FRE6 in Tape & Reel packaging is suitable for automated assembly processes and high-volume production environments where tape-fed component handling is standard. The RN60D4121FB14 in Bulk packaging is appropriate for manual assembly, prototyping, or applications where individual component handling is preferred.

Both parts maintain identical compliance status: RoHS non-compliant and REACH Affected. Both are qualified to military specification MIL-R-10509/1 and carry identical electrical ratings, temperature performance, and physical dimensions. The choice between these substitutes does not affect circuit performance, reliability, or regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can RN60D4121FB14 be used as a direct replacement for RN60D4121FRE6 in circuit applications?

A: Yes. Both parts are electrically and mechanically identical. The RN60D4121FB14 provides the same 4.12 kOhms resistance, ±1% tolerance, 0.25W power rating, and axial package configuration. The only difference is packaging format (Bulk versus Tape & Reel), which does not affect circuit performance.

Q: What is the difference between Tape & Reel and Bulk packaging?

A: Tape & Reel packaging supplies components on continuous carrier tape suitable for automated pick-and-place assembly equipment. Bulk packaging supplies loose components in containers suitable for manual handling and assembly. Both formats contain identical components with identical specifications.

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

A: No. Both parts share identical RoHS status (non-compliant), REACH status (Affected), and military qualification (MIL-R-10509/1). Compliance and certification status are identical across both part numbers.

Q: What determines substitutability for the RN60D4121FRE6?

A: Substitutability is determined by matching resistance value (4.12 kOhms), tolerance (±1%), power rating (0.25W), composition (metal film), temperature coefficient (±100ppm/°C), operating temperature range (-65°C to 175°C), axial package configuration, and physical dimensions (0.145" Dia x 0.344" L). The RN60D4121FB14 meets all these criteria.

Q: Can these parts be used in military or aerospace applications?

A: Both parts are qualified to military specification MIL-R-10509/1 and carry military-grade features including flame retardant coating and moisture resistance. Application suitability depends on specific system requirements and procurement specifications beyond component-level parameters.

Q: Is inventory availability a factor in selecting between these parts?

A: Inventory levels may influence procurement decisions. The RN60D4121FB14 currently has 1251 pieces in stock compared to 663 pieces for the RN60D4121FRE6. However, inventory status does not affect electrical or mechanical equivalence.
