Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1676349-5 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 47.5 kOhms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Power rating: 0.1W / 1/10W (exact match required)
• Temperature coefficient: ±10ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Parameters:

• Package / Case: 0805 (2012 Metric) (exact match required)
• Size / Dimension: 0.079" L x 0.049" W / 2.00mm x 1.25mm (exact match required)
• Height - Seated (Max): 0.026" / 0.65mm (exact match required)
• Number of Terminations: 2 (exact match required)

Compliance Parameters:

• Composition: Thin Film (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
• REACH Status: REACH Unaffected (exact match required)

All identified substitute parts meet these criteria and are manufactured by TE Connectivity within the RN73 series.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts—RN73C2A47K5BTD and RN73C2A47K5BTDF—are direct functional equivalents to the TE Connectivity 1676349-5. Selection among these parts is based on packaging and inventory availability:

1676349-5: Original part number with standard packaging configuration. Active product status maintained.

RN73C2A47K5BTD: Tape & Reel (TR) packaging. Active product status. Higher inventory availability (8,641 pcs in stock).

RN73C2A47K5BTDF: Tape & Reel (TR) packaging with additional suffix designation. Active product status. Lower inventory availability (817 pcs in stock).

All three parts carry identical electrical specifications, mechanical dimensions, and compliance certifications (ROHS3 Compliant, REACH Unaffected). Selection should be based on procurement requirements, packaging format compatibility with assembly processes, and lead time considerations.

Frequently Asked Questions (FAQ)

Q: Can RN73C2A47K5BTD be used as a direct replacement for 1676349-5?

A: Yes. Both parts are electrically and mechanically identical with matching resistance (47.5 kOhms), tolerance (±0.1%), power rating (0.1W), package (0805), and all compliance specifications. The primary difference is packaging format (Tape & Reel vs. standard packaging).
