Substitute Part Grouping Explanation

Substitution eligibility for the RN55D1304FRE6 is determined by the following critical parameters:

• Resistance value: 1.3 MOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Composition: Metal Film (exact match required)
• Package type: Axial (exact match required)
• Operating temperature range: -65°C to 175°C (exact match required)
• Physical dimensions: 0.090" Dia x 0.240" L (exact match required)
• Series compliance: MIL-R-10509/7 RN55 (exact match required)

The identified substitute part RN55C1304FB14 satisfies all critical electrical and mechanical parameters. The primary distinction between the main part and substitute is the packaging format (Tape & Reel versus Bulk) and temperature coefficient specification, which do not affect functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both RN55D1304FRE6 and RN55C1304FB14 are active products manufactured by Vishay Dale and comply with military specifications MIL-R-10509/7. Selection between these parts should be based on:

• Packaging requirements: RN55D1304FRE6 is supplied in Tape & Reel format suitable for automated assembly; RN55C1304FB14 is supplied in Bulk format suitable for manual assembly or small-quantity applications.
• Temperature coefficient tolerance: RN55C1304FB14 provides ±50ppm/°C stability compared to ±100ppm/°C for RN55D1304FRE6, offering superior frequency and temperature stability in precision applications.
• Inventory availability: Current stock levels are 1051 units for RN55D1304FRE6 and 766 units for RN55C1304FB14.

Both parts maintain identical RoHS non-compliant status, REACH Affected classification, and ECCN EAR99 designation.

Frequently Asked Questions (FAQ)

Q: Can RN55C1304FB14 be used as a direct replacement for RN55D1304FRE6 in circuit applications?

A: Yes. Both parts share identical electrical specifications (1.3 MOhms, ±1%, 0.125W), composition (metal film), package type (axial), operating temperature range (-65°C to 175°C), and physical dimensions (0.090" Dia x 0.240" L). The substitute part is functionally interchangeable in all circuit applications.

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

A: Tape & Reel (TR) packaging is used for automated pick-and-place assembly processes and provides components on a continuous carrier tape. Bulk packaging supplies loose components suitable for manual assembly or small-quantity applications. The component itself is identical; only the delivery format differs.

Q: Does the temperature coefficient difference affect substitution eligibility?

A: The temperature coefficient difference (±100ppm/°C versus ±50ppm/°C) does not prevent substitution. RN55C1304FB14 offers improved temperature stability, making it suitable for applications requiring tighter frequency or resistance tolerance over temperature variations. In applications where the original ±100ppm/°C specification is sufficient, both parts are equivalent.

Q: Are both parts compliant with military specifications?

A: Both RN55D1304FRE6 and RN55C1304FB14 comply with MIL-R-10509/7 military specifications and are classified as military-grade components with flame retardant coating, moisture resistance, and safety features.

Q: What is the inventory status for these parts?

A: RN55D1304FRE6 has 1051 units in stock; RN55C1304FB14 has 766 units in stock. Both are actively manufactured and available for procurement.
